The number of loops allowed in theory versatility. Unfortunately, this is but then severely restrict in practice. You can see the individual eyelets each not very onerous, because otherwise they damage in 'blink of' the very thin material and cut probably soon pass. One uses for strain relief several eyelets, the concept, however, works well.
More serious, the problem of fragile material, however, is in the fixing lugs. This one can not draw very firm, because the elongated holes in the tabs tear out very quickly! For me one of the holes is right on the first try, even though I have it applied only briefly to sample touched. I found that extremely disappointing!
Since they are the only restraints of this kind that I have found and the price was contrary to the slogans hope no superior quality, I have not sent back, and I will create in the future with much caution. I hope they keep for a while. Of course you would expect in this price range no professional equipment!
If you use them with caution, but they do their job very well! Therefore, instead of the three felt two star.
